One of the things that has struck me most about listening to Steve Jobs' biography on Audible is the amount of crying that goes on. Not just him but others - and not just others who he has made cry. People in all sorts of positions welling up in the face of the challenges and setbacks they faced.
It is all too easy to think that successful people have it easier than the rest of us or that they are so full of confidence that they sail through life's challenges. It is good to be reminded that they don't face any less difficulties than we do - they are just less likely to back away from them and they do what it takes to move forward. Repeatedly and no matter how scared they are.
